Right off the bat, the user interface is simple and easy to use. You turn the flashlight on using the rotary switch, which can be used to adjust the light intensity. 

There are four settings that you can choose from, Turbo, High, Med, and Low. They all provide varying degrees of light output. 

The charging point is in plain simple sight, located on the upper side of the flashlight. 

You can access the strobe and other brightness mode through a simple rotary switch.

When it comes to flashlights, some have user interfaces that are too difficult to COMBAT with. You don’t have all that time to study the manual and figure out how to turn your light on when you are FACED WITH A BEAR!

Performance and Modes

The PD40R V2 is a powerful piece of light producing a maximum of 3000 lumens covering up to 405 meters in front of you. That’s a total powerhouse considering the size.

This flashlight has four modes of brightness (low, medium, high, turbo), giving you good control of the level of light. The lumen count on each mode varies in performance with runtimes dependent on the mode in which the flashlight is operating in. 

This flashlight has a TURBO mode, which will illuminate your way up to 1328 feet. That’s about 405 meters. (Half a kilometer range?)

The max brightness setting of the Fenix PD40R V2 is most certainly a noteworthy feature of this flashlight.

That is quite the distance and range when it comes to flashlights. It is important that you pick a flashlight with a good beam distance. With almost half a kilometer of range, this flashlight can come of great use in various outdoor scenarios.

Here is a breakdown of every mode’s runtimes.

Other tactical flashlights in the market do not ALL use USB charging. Plus, the 18650 battery is even used in ELECTRIC CARS (Think TESLA.

The flashlight has a battery indicator that will turn red when it needs to be charged. While charging the indicator color is green, showing that it is being charged! 

Battery Indicator

The Turbo will work for 2.4 hours. The Fenix PD40R V2 will work for 3.1 hours when on the high setting. The medium setting will illuminate the streets before you for 8.3 hours, and on the low setting: 88.1 hours.

What’s great about this flashlight is that the batteries are rechargeable and replaceable, and there is a BATTERY INDICATOR, which will indicate the level of battery remaining on your light.

Most flashlights do not come with this feature, which is actually an excellent feature for any flashlight. Just have a glance at the battery indicator, and you will know precisely when to change batteries.

Anti-Slip Design 

This flashlight has a very good GRIP. It will hold true in your hand and won’t slip and fall even if it gets wet. 

The flashlight is designed with a pocket clip to fasten to your pocket. The size of this flashlight allows you to pocket it easily. (You can carry it wherever you like.)

Things You Need to Know About the Fenix PD40R V2 Flashlight

Fenix PD40R V2.0 on the grass

This flashlight is DURABLE and EASY to use. It isn’t one of those flashlights with Bluetooth speakers and an LCD screen to watch videos in. It is a simple flashlight that GETS THE JOB DONE! 

The color of the light is a cool white. Cool white color is considered the most soothing of colors for a flashlight (also the most useful.)

Depending on the mode that you choose, you can illuminate varied distances. The four-modes of this flashlight gives it VERSATILITY. 

The strobe mode is another excellent feature for when you need light signaling. 

The output of this flashlight is SATISFACTORY. With 3000 lumens of maximum performance, the Fenix PD40R V2.0 flashlight has sufficient brightness to light the woods with angelic brightness. 

THREE THOUSAND lumens are a whole lot of output for a little flashlight that is only a few inches tall. 

The battery is RECHARGEABLE, so you won’t have to keep buying new batteries and littering the planet. The package includes a USB charger cable that you can use to charge the battery. (No need to keep buying batteries.)

There are two battery options to choose from. You can either go with the 21700 lithium-ion battery or the 18650, which is even used in ELECTRIC CARS!

The switch is simple to use. It is a rotary switch which is a dial that needs to be spun to adjust the brightness. The rotary switch is also how to turn the flashlight off and on. 

Depending on your chosen mode, the battery will run for varying durations. The lowest mode lighting the flashlight for 88.1 hours. 

You must be careful of the TURBO mode; that thing eats up charge. Turbo mode will only run for 2.4 hours. IF you are going to go all out turbo, you WILL have to keep a bunch of spare batteries in your backpack (like when you go camping.)

Pros and Cons of the Fenix PD40R V2

This flashlight has a great set of pros, but a few cons are worth nothing. It is important that you consider the pros and cons of any product before you purchase it. 


The brightness levels of this Fenix PD40R V2 are most certainly a plus! At the highest level of brightness, it can illuminate close to half a kilometer before you. 

The LED light that is used offers HIGH OUTPUT!

The SWITCH has a simple and elegant design. The rotary switch is a handy addition to the Fenix PD40R V2. 

The strobe mode is yet another great addition to this flashlight. The strobe mode allows you to use the flashlight for light signaling. (STROBE MODE!)

With four modes of brightness to choose from, you can choose the mode of brightness that you require. (The Fenix PD40R V2 lights up the way with lights glowing, lights the moonlight nights with lights brighter than the darkest of nights!) 

The head of the Fenix PD40R V2 isn’t too big. The size of the head allows you to squeeze this flashlight wherever necessary. 

Plus, the features of this light are AMAZING! 

The fact that this light is WATERPROOF is a crucial selling point for any light source. Not only is the flashlight waterproof, but it’s bright enough to allow you to see in the rain. 

This light has a pocket clip that you can use to fasten this flashlight to your pocket or belt. 

Plus, it uses rechargeable batteries, which are totally GREEN. By green, we mean good for the planet. 

This flashlight throws light in varying degrees based on the setting. It throws 3000 lumens worth of light on the highest mode. If you would like to throw less light, all you have to do is lower the setting using the simple rotary switch. 

The Fenix PD40R V2 is made of High-Grade aluminum, which is used in mechanical work. You know, mechanical work like building boats and mechanical structures.

Hence you can throw this flashlight here and there, and it won’t break that easily. (DO NOT THROW IT DOWN THE EMPIRE STATE BUILDING, IT WILL BREAK!)

The charging time for a full charge is 3 hours. (This is excellent charging time – charging it a few hours every day or whenever necessary will suffice.) Plus, the battery indicator will show you the status of your light’s charge. Plus to Plus, it is charged using USB.

If there is any error with your Fenix light, you can claim the LIFETIME WARRANTY. (Any error)

This light is a breeze to operate! This flashlight is small and light; you can carry it anywhere… (really… carry it EVERYWHERE!)


There is no tail switch on this light, and neither does it have a switch that clicks. The click can be very important to many flashlight enthusiasts. 

Though the Fenix PD40R V2 is durable, I wouldn’t throw this flashlight down a set of stairs. It’s hardy for a flashlight but isn’t made of TITANIUM. (Unlike Kevin Hart?) 

The beam profile on the highest setting is good, but it drains the charge fast. Though you can power this flashlight with spare batteries, if the highest beam profile worked for a longer duration (2.4 hours) would have been better!

What Do Other Customers Have to Say?

Those that search for a good quality flashlight, one way or another, stumble onto a good product. You may have to go through a few useless ones and search the high seas.

Customers who have purchased this light had great things to say about it. Type-C charging was one of the most significant plus points for many customers. 

The measure of light was also satisfactory. People were satisfied with the range of measurements of this flashlight. 

The output was one of the biggest things that everyone was happy about. At the end of the day, the market is filled with lights that promise sound output but fail to deliver the output they promise. The performance of the Fenix PD40R V2 led to many customers who were happy with the output that was promised. 

Many that did review this light went on to say some great things about the Fenix PD40R V2. 

The power behind this tiny flashlight and the batteries were reliable. Most people were happy with the lighting this flashlight provided. 

My Experience With the Fenix PD40R V2

a human holding Fenix PD40R V2.0

My package arrived, and I was thrilled to review this flashlight. Promised to provide ample lighting to light the darkest nights, I was exceptionally impressed with this light.

The modes of light were adaptable. You could choose modes based on preference. The four modes all had good, varying degrees of light. The option to choose between four modes immediately sets this flashlight ahead of the rest for us. 

The output delivered by the tiny flashlight meant that Fenix was a brand we could trust!

The type-C charging was a brilliant addition to this light. Not all flashlights come with charging cables or the ability to charge. Plus, the batteries are not inbuilt. You can use spare batteries at will. 

My review of the Fenix PD40R V2 found the light to be HARDY and DURABLE with a good grip. 

Though the maximum time of illumination when set on the highest setting was only a few hours, I soon realized that I didn’t need to always use the flashlight on the highest setting. 

The low setting provided a good amount of illumination, which obviously had the ability to light the way for over 50 hours.
